Many of these courses are completely self-paced. The rest will start at various times later in September. You can find complete lists of the technology-related courses starting later in 2018 on Class Centrals Computer Science, Data Science, and Programming subject pages.

I've sorted these courses into the following categories based on their difficulty level:

Beginner

Intermediate

Advanced

Courses that are being offered for the first time are marked as new.

I understand this a long list and might be daunting for learners new to programming. In that case, you might find David Venturis recommendations for the best Data Science online courses useful even if you're not looking to learn Data Science. I hope to create more of these guides in the future. And finally if you have trouble figuring out how to signup for Coursera courses for free, don't worry written an article on how to do that, too.
